A reader was kind enough to let us know in the comments the LN46A550 in fact has 3 HDMI ports instead of just the one it mentions in the spec sheet online.  After carefully looking at it, Samsung only details the HDMI port on the side and neglects to mention the two on the back of the unit.

If you’d like to take a look at the manual of the LN46A550 yourself, you can find it here.
